Sukchan Lee 390a9dd637 [MME] incorrect behavior of the SGsAP 
1. According to ETSI TS 129 118 4.1, if the Network Access Mode (NAM) is set
   to "Packet only," no SGs association should be established.

2. If the NAM is set to "Packet and Circuit," and the SGs association is
   rejected by the CS core, this rejection should only impact
   the SGs association itself and not result in a UE attach rejection
   for a UE with a valid HSS account.

Sukchan Lee 668cc59f94 [AMF] Fixed 5GMM cause in Reject message (#1660) 
When a UE that requests slices tries to connect and there are no slices configured, the reject message is:

5GMM cause = 0x7 (5GS Services not allowed)

however it should be:

5GMM cause = 0x3e (No network slices available)

All 5GMM cause value in reject message is reviewed in this commit

Sukchan Lee 1bed0d5872 [#568] Add GTP-U Error Indication Handling 
So far, no operation was performed when Error Indication was received
from eNodeB. For that reason, I solved #568 issues by controlling
the MME to prevent this from happening.

Now, when GTP-U Error Indication is received, MME and SGW are implemented
to do what they have to do. I hope that the network can be restored
by responding appropriately even if Error Indication occurs.

Sukchan Lee 636170e0da Review ogs_expect() (#314) 2019-11-30 16:45:09 +09:00
Spencer Sevilla 5b59f09d9f ogs_assert to ogs_expects (#314) 
* HACK: Don't retransmit InitialContextSetupReq

Related: #256

* HACK: Don't use buggy sa1p_copy()  in eNBConfigTransfer

Related: #257

* mme: don't reject with 'IMSI is unknown in HLR' (permanent reject)

* MME: Implement S6a result -> EMM cause code mapping

Closes: #263

* Spencer: modification to Haralds fix because macros are now renamed

* MME: don't assert on MAC failures of uplink NAS frames

Closes: #267

* MME: Avoid ogs_assert() in many situations

We don't want to crash the entire program just because a message
received from an external entity didn't match some of our expectations.

* compiles fine, checked DIFFs and only difference is the ogs_assert -> ogs_expect
